BACKGROUND
Many risk factors for hip fractures have been suggested but have not been evaluated in a comprehensive prospective study.
METHODS
We assessed potential risk factors, including bone mass,… (More)

We previously described a putative creatine kinase M isoform in human sperm that is developmentally regulated and expressed during late spermiogenesis, simultaneous with cytoplasmic extrusion. We… (More)

BACKGROUND
Vertebral fractures are a hallmark of postmenopausal osteoporosis and an important end point in trials of osteoporosis treatment, but the clinical significance of these fractures remains… (More)

We developed a method for estimating the mean and standard deviation of ratios of normal vertebral heights from a sample that includes people with and without vertebral fractures. This method assumes… (More)

Women in China have much lower risk of hip fracture than women in Europe or North America but their risk of vertebral fractures is not known. Lateral spine radiographs, hip and lumbar spine bone… (More)

BACKGROUND AND METHODS
In postmenopausal women, the serum concentrations of endogenous sex hormones and vitamin D might influence the risk of hip and vertebral fractures. In a study of a cohort of… (More)

BACKGROUND
The relation between endogenous steroid hormones and risk for breast cancer is uncertain. Measurement of sex hormone levels may identify women at high risk for breast cancer who should… (More)

Quantitative ultrasound is a promising technique to evaluate fracture risk. To test the hypothesis that reduction of one ultrasound measurement, broadband ultrasound attenuation (BUA), is associated… (More)
